DRYING APPARATUS.

Specification of Letters Patent.

Application filed May 14, 1913.

Patented Jan. 20, 1914.

Serial No. 767,587.

To all whom it may concern Be it known that I, JOHN C. Bnnnnn, a citizen of the United States, residing at Lakewood, in the county of Ouyahoga and State of Ohio, have invented a new and useful Improvement in Drying Apparatus, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

My invention relates to a drying apparatus and is specifically adapted to the roasting of flexible pulp composition matrices, after such have received a type impression while in a slightly moistened condition.

The object of my inventive conception has been to provide an apparatus which while simple and economical of manufacture, can be readily manipulated and be otherwise more efficient than constructions until now available.

The inventive conception is embodied in means which are hereinafter explained and variously combined in the claims while the annexed drawing and particular description thereof together set forth in detail certain means constituting my invention, the disclosed means however, being but one of various mechanical forms in which the principle of my invention may be applied.

Figure I is a front elevation of an apparatus embodying my invention. Fig. II is a vertical section of Fig. I taken on a line front to rear and showing certain parts in elevation. Fig. III is a section on line III-III, Fig. II. Fig. IV is a section on line IVIV of Fig. II.

It will be seen that four corner standards a are provided. These standards are preferably of angular cross-section arranged in opposition to each other so as to inclose a rectilinear space. Near the bottom the standards a are provided with a plurality of intersecting braces a provided with central registering openings a for a purpose to be presently stated. Above, the standards a are furthermore fixed with relation to each other by an oven at". This oven is provided with a laterally elongated front opening 64*, and underneath this, with a smaller opening a, the purpose of both of which will hereinafter become obvious. The oven (4 is furthermore provided above and centrally with a stack a, while its bottom is provided with four outlying equi-spaced openings a. The braces a have depending from them a pivot bracket a of approximatcly U-shaped formation. The interjacent portion of this bracket supports two pivot blocks 11/ through which a pivot pin a projects.

Extending from one side into the oven a are a plurality, and in this instance, three gas pipes B. These are provided exteriorly with any acceptable type of valve I). Interiorly, their extent is to the medial line of the oven where they communicate with angle connections 6 thence to tees I) through each of which a pipe 5 provided with perforations extends. As will be readily understood from this description, the pipes b constitute burners for supplying heat to the oven. The lighting of such burners may be effected through the opening a.

Secured to the interior of the oven are a quartet of angle-iron brackets c, and resting upon such brackets so as to be disposed at the proper heating distance above the burners b is a plate 0. This construction accomplishes in effect a heating pan for the reception of a given amount of sand intended to be heated therein. Projecting up through each of the four openings a and registering openings a? in the four corners of the plate 0, is a short pipe length l), and these latter are fixedly secured in a depending position to the plate C through the medium of oppositely disposed bolts (l, as will be readily understood.

A foot pedal E is pivotally mounted intermedially of its ends through the medium of an opening c upon the pin (1.. The inner extremity of this foot pedal E is pivotally connected at c with an upwardly extending actuating rod (1 This rod in fact passes through the registering openings a which are intended as a guide therefor. The upper extremity of the rod 0'' supports through the medium of oppositely disposed nut formations c", bracket 0 This bracket has secured upon its upper surface two diagonally crossed members each involving an horizontally disposed portion 0 and two upwardly bent extremities c These four portions 6 extend through the four pipe lengths D, and are adapted to be reciprocated therethrough and guided thereby in a manner well known, by the actuation of the foot pedal E. The uppermost extremities of the portions 6 are provided with fixed collars e and superposed nuts 6 A grille member F in this instance formed of wire, comprises a fore and back length f each of which is provided at opposite ends with hook portions f curved in respectively opposite directions. It is these hook portions which are intended to be hooked around the portions 0 and secured between the fixed collars e and nuts 6 The lengths are connected by a plurality of intermedially extending transverse lengths f and a single parallel length f connecting the latter on a medial line.

The operation of my drying apparatus involves a depression of the foot pedal E. whereby the grille F is elevated as suggested in dotted lines in Fig. II. While in such an elevated position a matrix sheet is inserted through the opening a so as to rest upon the heated sand and thereafter the grille depressed so as to gravitationally rest thereon. After the matrix sheet has become sufliciently dried or roasted, the pedal is again depressed to permit of the withdrawal of the sheet and preparatory to the insert-ion of another.

My invention being thus described with sufficient thoroughness, what I desire to se cure by Letters Patent and therefore claim specifically, is:

1. A drying apparatus comprising a cas ing having an opening, a pan supported therein and beneath the plane of said opening, means for heating the latter, a plurality of members supported below and projecting above said pan, said members being movable in the direction of their respective axes, a grille mounted upon the upper ends of said members, and means for simultaneously actuating said members.

2. A drying apparatus comprising a casing, a pan supported therein, means for supplying heat thereto, a member movably secured below said pan and having upright portions projecting above the same, guides for said upright portions, a weighting member mounted between the upper ends of said upright portions, and means for actuating said first mentioned member.

3. A drying apparatus comprising a casing, a pan supported therein, means for heating said pan, a plurality of hollow members supported by said pan and projecting transversely with respect thereto, rods projecting loosely through said members respectively, a grille supported upon said rods, and means for actuating the latter.

4-. A drying apparatus comprising a casing, a pan supported therein, means for heating said pan, a plurality of pipe lengths rigidly suspended from said pan and projecting transversely relative thereto, rods loosely projecting through said pipe lengths and connected below, a grille mounted between the upper extremities of said rods and above said pan, and a foot pedal operatively connected with said rods.

Signed by me, this 13th day of May, 1913.

JOHN C. BREUER.
